DEV ven Anders Hiigedai, Soil-shaman, Sweden, designer to Evers 84 Co. Airtieholag. a corporation of Sweden Filed May 15, 1961, Ser. No. 11 9,5955 Claims priority, application Eweden May 1.9, Edi 7 Claims. (Qi. 16-375) The present invention relates to hinge devices designed to be used for separable obliquely inclining windows pivotal about a horizontal axis. More particularly, the invention relates to hinge devices of said kind comprising (for each of two opposite sides of the window) a single bearing pivot adapted to be attached to the window sash, said pivot being mounted in a bearing cup adapted to be attached to the adjacent side piece of the window frame, the radial section of said bearing cup on the inside and the outside being confined by such arcs of circles that the pivot is in radial direction movable into and out of said bearing cup.

The invention has for its principal object to provide a hinge device of this kind which will be very efiicient and advantageous in use and enable pivoting of the window from closed position to a position in which the outside of the window-pane will be within easy reach for cleansing by a person in the room.

Another object of the invention is to provide a hinge device by means of which the disengagement or removal of the bearing pivot from its bearing cup will be possible only when the window sash has been pivoted fromits closed position a predetermined angle.

A further object of the invention is to provide a hinge device of said kind which in the closed position of the window will present no hole through which, for example, cold air could pass from outside when the window is closed.

Still another object of the invention is to provide a hinge device of said kind in which the pivot will present a substantially plane outer surface when mounted in the window sash.

Other objects of the present invention will be made clear by the following description with reference to the accompanying drawings illustrating by way of example a preferred embodiment of the invention.

FIG. 1 is a side elevation of a side piece of a window frame on which the window cup and a stop bar belonging to the hinge device are mounted. FIG. 2 is a side elevation of the corresponding portion of the side piece of the window sash having the bearing pivot mounted thereon. FIGS. 3 and 4 are front views of the parts shown in FIG 1 and 2 respectively. FIG. 5 is a front view on a larger scale of the assembled hinge parts. FIG. 6 is a side elevation of the hinge device mounted in a portion of an obliquely inclining window in closed position with the bearing pivot and the guide part being sectioned and the window sash being shown by dot and dashed lines 2' in opened position of the sash. FIG. 7 is a view corresponding to FIG. 6 and showing the window fully opened.

In the drawings, 1 denotes the window frame and 2 the window sash. By means of screws 3 a bearing cup 5 is secured in a recess 4 in the outer side of the frame 1. The outer and inner sides of said cup in radial section being confined by arcs of circles not exceeding about 180 degrees with said cup being preferably substantially semicircular in radial section. Thus, on the side facing from the room said bearing cup is open, and it is also open in the axial direction. The arc-shaped edge of the cup facing to the window sash has a recess 6 extending along a small portion of said edge, and this recess in mounted position of the cup is positioned beneath the horizontal axial center line of the cup.

By means of screws 7 a plate or member 3 is attached to the sash piece 2 and said plate carries a horizontal hearing pivot 9 attached to or formed integrally with the plate. The bearing pivot is substantially semicylindrical corresponding to the bearing cup. Said pivot is preferably formed with a projection 1b the surface 11 of which constitutes an extension of the semicylindrical bearing surface of the pivot. In the normally closed position of the window sash the projection 10 constitutes the upper portion of the pivot. The plate or member 8 also carries a projection or stud 12 rigidly connected to said member and eceentrically positioned at some distance from the hearing surface of the pivot adjacent to the projection 10.

In the closed position of the window sash (FIG. 6) the upper portion of the sash is bearing against stop faces 23 of the frame 1, and from this position the sash is pivotal only in the direction of the arrow. The stud 12 is located at the convex outer side of the bearing cup 5 and the recess 6 is entirely covered by the pivot 9'. The plane surface 9a of the substantially semicylindrical hearing pivot 9 will be located in the same plane as the outer surface of the window sash 2 disregarding the small projection 16. This is an advantage in the use of covering sheets or plates for the sash and frame. If the sash be pivoted in the direction shown by the arrow of FIG. 6 the stud 12 in co-operation with the convex side of the hearing cup will serve as a guide member and prevent removal of the pivot from the bearing cup until the window has been rotated a certain predetermined angle as, for example, degrees in which position the stud 12 will re ister with the recess 5 as shown by FIG. 7 and enable detaching of the window from the frame, required.

It may be desirable to pivot the window sash through said angle for cleansing of the outer side of the window and it may be also desirable to provide means preventing disconnection of the window after pivoting thereof. For this purpose a stop bar 13 is provided on the frame, said bar being placed in a recess 15 in the side of the frame facing to the sash and slidable in the longitudinal direc tion of the side piece ll of the frame. By a reduced end portion 14 this bar extends through an aperture 16 in the bearing cup 5. In axial direction the portion 14 is located at some distance from the outer end surface 9' of the hearing pivot 9 as shown by FIG. 5. A stop pin or stud 17 is attached to the surface 9' adjacent to the projection 10 with said stud projecting axially and being intended to co-operate with the portion 14 of the stop bar 13 when the bearing pivot has been rotated to the position shown by dot and dashed lines in FIG. 6 thus preventing removal of the bearing pivot from the cup 5. In most cases this is desirable when the window is only intended to be pivoted an angle to the cleansing position for the outer side of the window but the window is not intended to be released from the frame. Said angle is only slightly smaller than the pivoting angle required for removal of the window from the frame.

In other cases it may be desirable or prescribed that the window shall be provided so as to enable a quick removal thereof from the frame in urgent situations. Such windows are termed catastrophe windows. In sucr cases the stop bar 13 shall not prevent removal of bearing pivot from the bearing cup.

In order to satisfy various demands in this respect, the stop bar 13 is adjustable and provided to be retained in two different positions. For this purpose said bar is provided with a U-shaped recess the base portion 18 of which extends in the longitudinal direction of the bar and the shanks of the U-shaped recess are denoted by l? anc 29 respectively. A pin or screw having a head is fastened to the frame 1 and extends through the recess 18-29. The bar 13 is movable so that said pin selectively may engage with the one or the other shank of the recess. When the pin 21 engages with the shank 19 of a the recess as shown by FIG. 6, the end portion 14 of the bar extends so far into the bearing cup said portion in co-operation with stud 37 will prevent rotation of the pivot 9 about angle large enough to permit the guide part 12 to pass through the recess s. in the engagement the pin 21 with the second shank 2% or" the recess (FIG. 7) the end portion 14 of the bar 13 has such a position in relation to the stud 17 that the pivot can be rotated a slightly larger angle to permit the guide member 12 to pass through the recess 6 and the disengagement of the pivot 9 from the bearing cup in this latter case the end surface 22 of the bar 13 forms a stop surface which in co-operation with the stud 1'7 prevents any continued rotation when the bearing pivot 9 moving from the closed position of the window has been rotated an angle iii-which the guide part 12 is in front of the recess 6 in the edge of the bearing cup.

After opening of the window sash a certain angle the stop bar 13 will be easily accessible by a person in the room for adjustment of the bar from the one to the second position. By means of the screw 21 or a screw for each shank of the recess ill-2d, the bar 313 may, if desired be secured in its position.

A hinge device of the kind described and shown is, or" course, provided at each of two opposite sides of the window.

By FlG. 3 it is shown that the bearing cup by one end portion 5 extends outside the frame 1. The object of this projecting end portion is to provide a protection against covering sheets on adjacent portions or" the roof or wall so that said sheets will not damage covering sheets on the outer side of the window sash if such sheets are used.

The invention is not restricted to a hinge device having in its details the form shown in the drawings but the form of the details may be varied without departing from the spirit of the invention.
